Local cluster effect in different traffic flow models

A comparison of diverse effects of self-organization in traffic flow in microscopic and macroscopic traffic flow models is made. It is shown that traffic flow models which are mathematically different, belong to the same universality class of traffic flow models in the sense of their possibility to reproduce properties of real traffic jams, if they show the complete properties of the local cluster effect in traffic flow found out by Kerner and Konhäuser in 1994.
